APPARATUS FOR DRYING AND STEAMING GRAIN.

Specification of Letters Patent;

Patented Oct. 4, 1910.

application filed February 26, 1910. Serial No. 546,073.,

Be it known that I,-PE'TER PRovos'r, acitizen of the United Stat-es, residing at-Mile waukee, inthe county of Milwaukee and State of Wisconsin, have invented a new and useful Apparatus for DryingandSteaming Grain, of which the following is a specification. 1

This invention relates to apparatus for drying and steaming grain and is more particula'rly an improvement upon the structure disclosed in Patent No. 940,190, issued to me on Noveniber 16,4909.

One of the objects of the present invention is to provide means whereby the grain qgnbe slightly retarded during its passage rough the tubes'anddischarged in rela tively small jets into a steaming chamber,

means being utilized whereby each of the jets can be spread so as to insure the proper steaming of all of the grain. K

Another object "is .to provide improved means for directing steam into the steaming chamber and for spreading it evenly therein. A further object is to provide a machine of this class having means whereby the tubes can be thoroughly heated-during the passage o t the grain therethrough and thus dried prior to the discharge thereof into the steammg chamber. With these and other objects in viewj the lnvention consists in certain novel details of inafter more fully in the claims.

In the accompanying drawings the pre ferred form of the invention has been shown In said drawihgsi-Tigure *1 is a central vertical section through a combined grain drier and steamer constructed in accordance with the present invention. Fig 2 is a planview thereof. Fig. 3 is a section on line A-B, Fig. 1. p l

Referring. to the figures by "characters of reference, 1 designates a casing, preferably cylindrical, the bottom of said casing being hopper with a large outlet opening 3. The feed end of the casing is closed by a head 4: having a plurality of conical depressions therein, 1ndicated at 5, there being an opening in the bottom of each depression as indicated at 6." and said opening being desi ned todi'rect material into tube 7 securecfat one end to the head 1 and extending; around the opening. A number of these tubes are utilized,

shaped as shown at 2 and provided they being extended longitudinallywithin the casing and being mounted at their lower ends within, a partition plate 8 extending transversely within the casing. A frame 9 may be supported the upper end of the casing and rods 10, such as disclosed in my patent heretofore referred to may be suspended from this frame and Wltlllll the tubes each rod carrying a series of deflecting devices 11'.

Arranged within the casing and below the partition plate 8 isaa disk '12 which is suitably supported in a fixed position relative to the tubes thereabove, said disk being frusto conical depressions 13 each of which opens depressions and tubes are located directly under thetubes 7 and 'a frame 15 is movably ot/grain therethrough. The space between the disk 12 and the chamber as indicated at v 18. Arranged within the center of this chamber is acuplike casing 19 having a drain pipe 20 extending from the bottom thereof and beyond of which is provided with a plurality of apertures 22, there being a drain-opening 23 in the bottom of the nozzle and above the pipe 20. A supply pipe 24 opens into the nozzle 21 anda conical deflector 25 exnear. the upper end-th' :eof and an outlet pipe 27 extends from a casing at a point above the partition 8. it is of course to be understood that these various pipes are provided .with valves whereby. the passage of steam through them can be controlled.

. When it is desired to use this apparatus for drying grain; steam is admitted into the interior of the casing 1 through either vor ,both of the pipes 26 andthe tubes will thereprovided-with a series of hopper like or bottom of the caslng 1 constitutes a steamingone side of the casing 1. Mounted withih the casingL19 is a nozzle 21, the upper end into a short hanging tube 14. These mounted below the short tubes 14 and carries a plurality of conical valves 15, each tends over the casing 19 and the nozzle. .Steam inlet pipes26 opcn into the casing 1 viously all of the grains will each depression having 1 65 communicating therewith and depending 5 by, the deflectors 11 serving to deflect the grain against the walls of the tubes. The grain will then be discharged from the lower end of the tubes and into the depressions 13 from which it will pass through the reduced tubesl to the interior of the chamber 18 from which it will pass outward throughthe opening, 3. Should it. be desired to utilize the apparatus for steaming grain, the steam is shut oil from the pipes 26 and admitted through pipe 2 1 to the nozzle 21. It will thus escape through the upper apertured end of said nozzleand'into the hood 25 which will spread the steam outwardly within the chamber 1 8. The grain in pass- 20 ing ddwnward through the tubes will be discharged in small jets through thereduced tube let and be spread by thevalves 15 so as to fall broadcast through the chamber 18 and thesteam contained therein. Ob-

thus be acted upon by thesteann It is of course tdbe understood that variouschanges maybe made in the construc-' tion and arrangement of the parts, without departing from the spirit or sacrificing any of the advantages of the invention.

hat is claimed is I 1. Apparatus of the class described including a casing, a partition therein having hopper like depressions, there being tubes depending from and opening into said depressions, parallel tubes'within the caslng and above, and in vertical alinement with the depressions in the partitions, said tubes 40 being spaced from the partition, a spreading device below each of the tubes depending from the depressions, and means forsimultaneously shifting said spreading devices toward'or away from the partition.

- and adapted to, direct grain into the depressions, a valve below each of the tubular extensions, and means'for simultaneously adjusting said valves toward or away from the extensions, each of the extensions being of less diameter than the tube thereabove.

3. Apparatus of the class described in- :cluding a casing, having an upper heating compartment and a lower steaming compartment, tubes extending through the heating compartment, and open at their, ends, a partition a within the steaming compartment. and

having depressions, one of said depressions being arranged below each of the tubes and 2. Apparatus of the class described in-- a tubular portion.
